Have the ability to use a mySQL server to store/retrieve user, rank and ban data instead of the flatfile system ULX currently uses.
Simply, this would allow multiple servers to share the same group/user/ban pool.
I know this would be a large change to ULX, but it wouldn't hurt to have it in the pipeline right? heh
MySQL ist not officially supported by gmod, so I won't support it in ULX an so often used admin mod too.
